Abstract
Method of and apparatus for spinning yarns from staple fibers in an air vortex in a stationary spinning tube axially coupled by one of its ends to a stationary air chamber, and by its other end to a sub-atmospheric pressure source. A flow of discrete fibers is supplied into the air chamber onto the wall of an air vortex which entrains, doubles and densifies the fibers before they are taken onto an open end of yarn which is given an additional twist while being withdrawn in the region between the air chamber and a take-off device. A fiber supply duct which opens into the air chamber is oriented toward the wall of the air vortex, an additional twisting device being provided between said twisting device and said air chamber.
